The data class of kotlin greatly simplifies our programming code because of its internal encapsulation of getter and setter methods but at the same time it cant rewrite getter.
Sometimes you just need to create classes to hold data like structs in the C programming language. Join millions of learners from around the world already learning on Udemy. My advice is it cant be done dont do it.
